The Economist-A Growing Number of Countries are deciding to Ditch Prohibition. What comes Next?

IN AN anonymous-looking building a few minutes’ drive from Denver International Airport, a bald chemotherapy patient and a pair of giggling tourists eye the stock on display. Reeking packets of mossy green buds—Girl Scout Cookies, KoolAid Kush, Power Cheese—sit alongside cabinets of chocolates and chilled drinks. In a warehouse behind the shop pointy-leaved plants bask in the artificial light of two-storey growing rooms. Sally Vander Veer, the president of Medicine Man, which runs this dispensary, reckons the inventory is worth about $4m.

America, and the world, are going to see a lot more such establishments. Since California’s voters legalised the sale of marijuana for medical use in 1996, 22 more states, plus the District of Columbia, have followed suit; in a year’s time the number is likely to be nearer 30. Sales to cannabis “patients” whose conditions range from the serious to the notional are also legal elsewhere in the Americas (Colombia is among the latest to license the drug) and in much of Europe. On February 10th Australia announced similar plans.
